Introduction
The kV RSX Communications Board is an
optional factory-supplied addition to the kV™
Meter, or may be ordered in the form of a
retrofit kit to upgrade “Communication
Ready” kV™ Meters. Meters that are capable
of being upgraded may be identified by the
words “Modem Ready” on the upper
nameplate of the meter.
The kV RSX Option Board is used to provide
two-way communication to the kV™ Meter
and may be used on S-base, A-base, and
switchboard meters. It is available on both
TOU and demand versions of the kV™
Meter.
The kV RSX Option Board may be used in
conjunction with other GE option boards,
which provide a three-phase power supply,
load profile recording, and input/output
functions. If required, the flexibility of the
kV™ Meter makes it possible to combine all
of the above option boards in a single meter.
The kV RSX Option Board has three
modes of operation: External Modem
mode, RS-232 Simple Serial mode and
RS-485 Simple Serial mode.
When operating in External Modem Mode,
the kV RSX provides an RS232 interface to
an external telephone or wireless modem to
facilitate remote kV Meter reading and
programming. In this mode the kV RSX
contains AMRA
tables which can be
programmed to provide the following basic
features:
•
300, 1200, 2400, 4800, 9600 baud
support.
•
Supports industry standard
protocol and AMRA Tables
•
Originate call on an event
•
Originate call on a scheduled basis
•

power
RS-485 Simple Serial Mode provides a halfduplex, 2 -wire, RS-485 interface for remote
reading of the kV Meter. The baud rate is
fixed at 9600 bps. No multidrop capability is
supported.
All kV™ Meters, including those with kV RSX
boards, are programmed using GE’s
MeterMate software program.
kV RSX Features,
External Modem mode
The kV RSX External Modem mode features
can be broken down into those features that
apply only to when the meter originates a call
(call origination), the meter answers a call
(call answer), or standard features that apply
to all call types.
Data Rate
The kV™ RSX Option Board can be
programmed for a DTE baud rate of 300,
1200, 2400, 4800, or 9600. This is the baud
rate at which the option board will
communicate to the attached, external,
modem.
Setup Strings
The kV™ RSX Option Board is shipped with
default external modem setup strings.
However, should it be necessary for you to
change the modem’s setup strings, they may
be changed by using GE’s MeterMate
software program.

Page 6
determined by contacting your local
telephone company.
Call Origination
Introduction
The kV™ Meter is capable of originating a
phone call for the following reasons:
• Scheduled data call
• Event (i.e. errors, cautions, diagnostics)
• Power outage (optional)
• Power restoration
• Test call
(1-15 minutes) between each call cycle
(primary/secondary phone numbers). If a
connection cannot be established after the
programmed number of call cycles, the
modem will wait four (4) hours and repeat
the process.
A programmable retry limit is provided that
can limit the total number of times the above
algorithm will be repeated before the meter
no longer attempts to call. The kV Meter will
default to two (2) times through the retry
algorithm unless changed using GE’s
MeterMate Software.
The retry algorithm does not apply to power
outage calls or to test calls.
Programming Phone Numbers
Call Origination Window
The kV™ Meter can store up to three (3)
phone numbers that can be selected by the
meter to place a call to the host software
system. There are five (5) possible ways call
origination can take place. These are
scheduled data calls, event calls, power
restoration calls, test calls, and power outage
calls. Each call type may have both a
primary and secondary phone number. The
primary phone number will be attempted
first, and if no connection can be established,
the meter may then either try the secondary
phone number or go into retry mode (see
below) if no secondary phone number exists.
Phone numbers may be reused (i.e. a single
phone number can be used for all primary
numbers).
A call origination window can be established
that will limit when the kV™ Meter can
originate a call. This window can prevent the
kV™ Meter from making phone calls when a
voice user is likely to need access to the
phone.
Each phone number may be up to 38
characters in length to allow for credit card
calls and other calls requiring long phone
numbers.
Retry Algorithm
If the kV™ Meter attempts to originate a call
using the primary phone number but is
unable to establish a connection for any
reason, it will immediately attempt the
secondary phone number, if supplied. If a
connection cannot be established using this
phone number either, the meter will enter the
following retry algorithm:
The meter will attempt to dial both the
primary and secondary phone number (if
present) up to a programmable five (5) times
each, waiting a random number of minutes
The call origination window is specified as a
start and stop time (HH:MM) on a particular
day of the week, combination days of the
week, or every day of the week. It is not
possible to have different call origination
windows for different days of the week.
Because the kV™ Meter can originate a call
for the purpose of communicating data,
errors/cautions/diagnostics, and reporting
power outages, some control is provided to
customize the kV™ Meter to best meet the
needs of your customer. The kV™ Meter can
be configured to apply the call origination
window to data calls, error/caution/diagnostic
calls, or both types of calls. The call
origination window is not applied to power
outage calls or to test calls.
Note: Demand only kV meters can not
have a call origination window
Data Calls
The kV™ Meter can be configured to
originate a call to report data to the host
software. The meter may be programmed to
originate a call in one of two ways:
1. Call at a specified time and day of the
week - this option enables a call to the host
Page 7
software on a particular day of the week,
combination of days of the week, or every
day of the week at a single specified time.
Using this option, the maximum number of
data calls per day is one.
2. Call on a specific date and time - this
option enables calls to occur on a specified
date at a specified time. Only one date and
time will be stored in the kV™ Meter,
therefore, this field will need to be
reprogrammed during each data call.
The kV™ will attempt to dial the
primary/alternate phone numbers that have
been
programmed
into
the
“Primary/Alternate Data Phone Number” field
using GE’s MeterMate Software.

Manager - Quality and EHS, GE Meter,
130 Main Street, Somersworth, NH
03878-3194, Telephone number (603)
749-8550.
Note: Data calls can not be scheduled on
demand only kV™ Meters
Event Calls
The kV™ Meter can initiate a call to the host
software whenever an error, caution, or
diagnostic is detected by the meter. Using
GE’s MeterMate Software, the kV™ Meter
can be customized to call in on all or
selected events.
The kV™ Meter will attempt to dial the
primary/alternate phone numbers that have
been
programmed
into
the
“Primary/Alternate Event Phone Number”
field using GE’s MeterMate Software.
Power Outage Calls (optional)
The kV™ Meter can be equipped with an
optional dual-cell lithium battery to provide
power outage notification. The life of the
battery will depend on several factors
including the number of outages and the
duration of outages before an outage call is
placed. Under typical use, the battery can be
expected to last for at least fifty (50) phone
calls.
Soft Switch
The optional power outage call feature is
controlled by a Soft Switch. Unless activated,
the power outage feature is not enabled. The
Outage Soft Switch can be purchased by
contacting
your
local
GE
sales
representative. All meters ordered with the
optional power outage call feature will be
supplied with the Outage Soft Switch
enabled.
Outage Definition
The length of time that power must be out
before the kV™ Meter places an outage call
to the host software is programmable from
zero (0) to two hundred fifty-five (255)
seconds. The default time is zero (0), which
means that an outage call will be attempted
as soon as the kV™ Meter goes into power
down mode. This timer should be used for
reference only and is accurate to ± 10%.
Battery Indicator
The kV™ Meter will attempt to dial the
primary/alternate phone number that have
been
programmed
into
the
“Primary/Alternate Outage Phone Number”
field using GE’s MeterMate Software.
It is possible to test the kV™ Meter’s optional
power outage battery. This is a pass/fail test
and is only performed when initiated by the
host software during a communications
session with the meter.
Page 8
Outage Retry Algorithm
If the kV™ Meter outage call to the primary
phone number is unsuccessful the meter will
delay for 2 minutes, then attempt to call the
alternate phone number, if provided.
Alternatively, it will retry the primary number.
If both calls are unsuccessful, the modem
will power down and make no further
attempts to dial the host software.
on a particular day of the week, combination
days of the week, or every day of the week.
It is not possible to have different answer
window for different days of the week.
Note: Demand only kV™ Meter cannot
have an answer window and will behave as
if the answer window is always open.
Number of Rings
Power Outage Delay
A programmable timer is provided with the
optional power outage call feature that can
be used to minimize the number of power
outage calls made by a particular meter for
the same outage.
If enabled, the kV™ Meter will only initiate a
power outage call to the host software after a
programmable timer has expired. The timer
will be initiated after power restoration and
must expire before a power outage call is
initiated. If a power outage occurs before the
timer has expired, no outage call will be
placed and the timer will be reset. This timer
can be configured between zero (0) and two
hundred fifty-five (255) minutes with zero (0)
disabling this feature.
Power Restoration Calls
The kV™ Meter will call the host software
when power has been restored following an
outage if enabled.
Test Calls
Using GE’s MeterMate software and an
optical probe, the kV™ Meter can initiate a
test call to a designated phone number. A
test call may also be initiated over a remote
connection. The call will take place after the
remote session has ended.
The kV™ Meter can be configured to answer
after a programmable number of rings.
Separate limits are provided for the number
of rings before answering for both inside and
outside the answer window.
The number of rings is programmable from
zero (0) to two hundred fifty five (255) where
zero (0) will cause the meter to ignore all
incoming calls.
Answer Lockout Timer
For situations where the kV™ Meter will be
sharing the phone line with a voice user, the
Answer Lockout Timer may be used. This
feature, when enabled using GE’s MeterMate
Software, will cause the kV™ Meter to not
answer incoming phone calls, for a
programmable period of time (0-255
minutes), after it has answered a call but was
unable to establish carrier.
This feature enables a voice user to gain
access to an incoming voice call without
having the meter intercept the call.
Note: GE recommends that the Answer
Lockout Timer be disabled (set to zero)
when the meter is not sharing the phone
line with a voice user.
Call Answer
The kV™ Meter is capable of answering calls
from the host software.

Data Rate
Installing the kV RSX
in the kV™ Meter
The kV RSX Option Board can only be
installed in “Modem Ready” kV™ Meters.
These meters can be identified by the words
“Modem Ready” which are printed on the left
side of the meter nameplate.
Any combination of the four (4) option
boards may be installed in the kV™ Meter at
one time. These include the I/O-2
Input/Output option board, the LP-2 Load
Profile option board, the kV RSX Option
Board, and the RG-1 Revenue Guard option
board. The I/O-2, LP-2, and kV RSX Option
Board can be combined in an option board
“stack” if necessary.
See Figure 1 for
details.
Page 10
Figure 1: Option board stack
The Revenue Guard option board is not part
of this stack and is not affected by the
presence of other option boards.
Note: The kV RSX Option Board must
always be installed as the inner most option

Testing Meter
Calibration
If the kV RSX is in simple serial mode,
meter calibration can be tested in kV RSX
equipped kV™ Meters as outlined in the
kV™ Meter Installation, Operation, and
Maintenance Guide, GEH 5081B. If the kV
RSX is configured in the external modem
mode, a compatible external modem must
be connected to the kV RSX
communications cable before powering on
the meter to perform calibration. It is
recommended that 20 seconds of settling
time be allowed, after applying voltage,
before making accuracy measurement or
placing the meter into test mode. Users will
see “busy” on the LCD display approximately
17 seconds after voltage has been applied to
the meter. Once the display returns to its
normal scroll, it is safe to begin accuracy
measurements or to place the meter into test
mode.
Meter Installation
The kV™ Meter must be connected to the
external communications device through a
means which will provide both a secure
connection and ease of disconnection for
troubleshooting, meter change out, etc.
Important:
Under no condition should
the communications line be run in a
conduit with power lines or exit the meter
enclosure via the same nipple as the
power lines. Also, for the case where
other optional signal lines are taken from
the kV™ Meter, these other lines should
not be bundled with either the power
lines or the phone line.
For A-base meters, the connection to the
customer
supplied
communications
equipment should be done in a similar
manner. The communications cable for the
A-base terminal block should be taken
immediately to a separate enclosure
dedicated to this specific application.
Test Call
The kV™ Meter equipped with a kV RSX
operating in external modem mode can be
prompted, using GE’s MeterMate Software,
to place a test call to one of the three (3)
phone numbers stored within the meter. The
test call may be initiated using the optical
port or over a remote connection. A red LED
is provided on the kV RSX board that can be
seen from the front of the meter (see Figure
14: kV RSX LED location) and is used to
monitor the progress of the call.
All kV™ Meters with kV RSX option are
supplied with an insulated communications
cable which extends approximately 30
inches out the base on S-base meters and
out of the side of the case on A-base meters.
The communications cable may be
terminated in either an RJ-11 or a DB-9
connector plug.
The communications cable should exit the Sbase meter socket enclosure by the most
direct means and be connected to the
customer
provided
communications
equipment external to the meter enclosure.
Usual practice has a short conduit nipple
extending from the meter enclosure to a
separate, dedicated enclosure where the
external modem is located.
Figure 14: kV RSX LED location
An LED will illuminate when the kV™ Meter’s
external modem
has established a
Page 17
connection
and carrier detected. By
monitoring this LED (as well as any LEDs on
the external modem), correct operation of
the kV RSX, can be verified during meter
installation.
Note: When the kV™ Meter is first
energized at the installation site, the carrier
detect LED will illuminate to indicate that
the kV RSX is properly powered. After the
kV RSX is initialized, the carrier detect LED
will go out. If the LED stays illuminated for
more than 5 seconds, the kV RSX board is
defective and should be replaced.

Appendix
External Modem Mode
For correct operation in external modem mode, the kV RSX requires that the operating mode
jumpers be positioned correctly, an external modem be connected to the communications cable
and the setup strings and baud rate be correct for the modem. At the time of power up, the kV
RSX initializes the external modem. If the modem is not present or the set up strings or baud
rate are incorrect, the kV RSX will continue to try to configure the modem. The Modem
Configuration Error bit, in the End Device Mode and Status table of the kV RSX, will be set if the
kV RSX cannot properly configure the external modem.
kV RSX Setup Strings
In External Modem Mode the kV RSX has programmable setup strings which serve to: reset the
external modem device to a known state, initialize it for communications with the kV RSX, setup
call answering and call origination configuration parameters.
External Modem Reset String
The kV RSX is designed to interface with many different external modem devices both domestic
and foreign using telephone or wireless technologies. Because there is no common method of
resetting these various external modems to a known state, the kV RSX provides a programmable
reset string.
Connecting the kV RSX to an external telephone modem will require the use of a 9 pin female to
25 pin male D-sub adapter such as Inmac part #37101 or Global Stock No. THC4496.
Before putting the kV Meter into service it is important to know the reset string and reset state of
the external modem device connected to the kV RSX. The majority of external modem devices
can be reset to their user programmed state by the string "ATZ". This 'z' is the default reset
string value for the kV RSX. Some modems have several user programmed profiles, in which
case the Z is appended with a number to load the desired profile.
Most modems can be reset to their factory default state by "AT&F". If this is the case and the
factory state is desired the 'z' should be reprogrammed with "&F". Some modems have several
factory default profiles, in which case the &F is appended with the number of the desired state.
Some wireless modems only emulate the telephone modem AT command set and do a good job
of resetting themselves on power up. Sending an AT reset command to these modems may
start an undesired, lengthy channel reacquisition process. In these cases it may be best to
program the reset string to all blank characters. This will prevent the kV RSX from sending a
reset string.
In configuring the external modem device to work with the kV RSX it is important to know what
resets the modem and what the reset state is.
Initialization String
The programmable kV RSX initialization string is used to set the external modem to a
configuration required by the kV RSX to control the modem. There are six (6) main functions
that are programmed through the initialization string. These are listed below along with the AT
command that sets the desired configuration in popular telephone modems.
Page 20
Local Echo - Local echo of modem commands must be set to off (E0).
On/Off Hook Control - The external modem is initialized to on hook (H0).
Modem Result Messages - Configure the modem to respond with AT command result
messages (Q0 ).
Format of Result Messages - Configure the modem to respond with text rather than numeric
result messages (V1).
Carrier Detection - Configure the modem to control the carrier detect RS-232 signal line based
on the presence of the carrier signal (&C1 ).
Data Terminal Ready - When using the DB-9 terminated communications cable, configure the
modem to go to go on hook and assume the command mode when DTR is toggled (&D2). If the
RJ-11 communications cable is used, configure the modem to override the DTR state (&D0)
because this cable does not support the DTR signal line.
The default setting for the initialization string is E0H0Q0V1&C1&D2. This should be changed for
cases where the modem in question does not support the default commands. In these cases, the
equivalent command for the modem of interest should be substituted. For external modems
that support error control it is necessary to disable the error control. The AT command to
disable error control should be appended to the initialization string. For external
modems that support data compression and flow control it is necessary to disable both
data compression and flow control. The AT commands to disable data compression and
flow control may be appended to either the initialization string or the Call Answering and
Call Origination Strings. See table 6 for recommendations.
Call Answering Strings
The kV RSX contains two 20 byte strings which can be programmed to accept AT commands
which pertain to configuring the external modem to answer incoming calls. These are initially set
to all spaces.
Call Origination Strings
There are four 20 byte strings which can be programmed to accept AT commands which pertain
to configuring the external modem to originate outbound calls. These are initially set to all
spaces.
CAUTION: The following modem options should NEVER be placed in any meter
modem setup string as you may prevent successful communication with the
meter:
& commands:
S-registers:
Dial modifiers:
E1, H1, Q1
&Sn, &Tn, &Vn, &Wn, &Yn, and &Zn
s3, s4, s5, s14, s16, s21, s23, s24, and s27
s=<n>
Baud Rate
The rate that the kV RSX communicates with the external modem (DTE rate) is configured
through programming of the Answer Baud Rate and the Originate Baud Rate in the kV RSX
AMRA tables. The initial baud rate used to setup the external modem is the Answer Baud Rate,
which is set to 9600 bps at the factory. The Originate Baud Rate also defaults to 9600 bps.
Unless the external modem operates at speeds slower than 9600 bps, these values should
remain at there initial settings. When using slower speed modems it is necessary to reprogram
the Answer and Originate Baud rates to the speed of the modem. For slower DTE speeds it is
necessary to put E0 in the modem reset string following the modem reset command(s).
Page 21
If the answer (and/or originate) connect baud rate is to be other than the DTE rate or if a
particular answer (and/or originate) connect baud rate is desired it must be configured through
the answer (and/or originate) modem string. The RSX will not adjust its DTE rate to that of
the negotiated connection baud rate. This is not a problem for those modems which fix
the DTE rate regardless of the connection rate (DCE rate). For modems that adjust the
DTE rate to the connection rate, the connection rate should be fixed to the DTE rate
through the use of appropriate Call Answering and Call Origination setup strings. See
Table 6 for recommendations.

RS-232 Simple Serial Mode
RS-232 is used extensively for communications between computers and peripheral devices such
as the mouse, keyboard and etc. Another example is the use of the RS-232 port on a computer
to communicate with the kV meter using the Smartcoupler. The kV RSX, in RS-232 mode,
provides a straightforward, isolated, connection between the kV Meter and the host device. The
permanent connection of the kV Meter to a personal computer, for continuous data collection, is
an example.
The most convenient way to connect the kV RSX to a computer is to connect the kV RSX DB-9
communications cable to the computer's RS-232 port through a 9 pin null modem cable. It is
important to select a null modem cable that is shielded and that the end device (computer)
provide a path from this shield to ground. The shell of the kV RSX DB-9 connector is connected
to the shield which surrounds the wire in this cable. The RS-232 communications distance is
limited to 50 feet.
Figure 17 RS-232 Connections for the DB-9 Cable.
Figure 18 RS-232 Connections for the RJ-11 Cable.
Page 25
RS-485 Simple Serial Mode
RS-485 communications use differential voltage signals to improve on the noise immunity and
distance limitations of RS-232. When fully implemented, RS-485 enables many devices to
share a single communications bus. The kV RSX implementation of RS485 is point to point, with
no multi-drop capability at this time. It is useful if the communications distance is greater than
the 50 feet provided by an RS-232 link. Also, RS-485 communications are more immune to the
disturbances that are experienced in an electrically noisy environment.
The kV RSX communications cable does not connect directly to a computer port, although some
embedded controllers have a dedicated RS-485 port. Typically, an RS-485 Serial Interface Card
is installed in the host computer to provide the correct RS-485 signals over a twisted pair of
wires. The connection to the kV RSX is half duplex, using two wires. For half-duplex, the signal
lines marked RX+ and TX+ must to be connected together and the signal lines RX- and TX- must
be connected together, as shown in Figure 20. Terminating resistors are not required for this
application and should not be used.
The kV RSX, RS-485 communications, have been tested using a host computer and the
RS422/485 Serial Interface Plus, Part # IC050C. This serial interface card is made by:
Black Box Corporation
P.O. Box 12800
Pittsburgh, PA 15241
Though not yet tested with the kV RSX, other serial interface cards and RS-232 to RS-485 signal
converters are available from:

The EIA-485 standard does not specify a standard connector for RS-485 communications.
There are two styles of communications cables available for the kV RSX. One is terminated with
a DB-9 connector and the other with a “telephone type” four conductor RJ-11 connector. If the
environment is electrically noisy, use of the kV RSX DB-9 communications cable is
recommended. The shell of the DB-9 connector is connected to the shield which surrounds the
wire in this cable. Over the run of the cable, the shielding should be continuous to the end
device, where it should be grounded.

Determining the Mode of an Installed kV RSX
The kV RSX option board is not detected by the meter in either RS-232 or RS-485 simple serial
modes. There are no tables in the option board when it is in either of the simple serial modes.
There is no way to read the meter and find out what mode the option board is in. The mode can
be determined by observing the LED at the time of power up, one (1) blink for external modem
mode, two (2) blinks for RS-232 simple serial mode, and four (4) blinks for RS-485 simple serial
mode.
If it is not possible to cycle the power to observe this LED and the mode is not known, the mode
can be determined through process of elimination. First, read the kV meter using the
Smartcoupler and determine whether the kV RSX is detected by the meter through reading the
GE Device Table, installed options field. If using MeterMate, the presence of the kV RSX will be
reported if the board is in external modem mode. If the meter is detecting the kV RSX, then the
option board is in external modem mode. Otherwise, the kV RSX is in one of the two (2) simple
serial modes. To determine if the kV RSX is in RS-232 simple serial mode, try reading the meter
using a null modem cable connected between a PC and the communications option board. If the
meter can be read this way, it is in RS232 simple serial mode. If this fails, the kV RSX option
board is in the RS-485 simple serial mode.
Page 28
Using MeterMate Version 2.12 with the kV RSX
MeterMate 2.12 can be used to build programs for both the kV Modem and the kV RSX option
boards. The following instructions pertain to building MeterMate programs for the kV RSX option
board operating in the external modem mode of operation.
Default MeterMate Program for kV RSX
Begin by creating a basic kV RSX default program from which all kV RSX programs will be built.
This process assumes that the default MeterMate programs have not been modified since
MeterMate was installed.
Begin by starting the MeterMate Windows program builder. Select Editors, Modem Option
Editor, Table Name “Default”. After the Modem Option: Default screen opens, edit the Modem
Configuration form so that it appears as follows:
Save this modified table with the table name “RSXdef”. Whenever building a new kV RSX
MeterMate program, select the “RSXdef” Modem Option Table as a starting point.
Page 29
External Modem Reset
Under the Call Answering options, the RSX Reset setup string defaults to z. This sends an ATZ
to the external modem to set the external modem to its stored profile. If the factory, rather than
the stored profile, is desired change the RSX Reset string to &F. In this case the Modem
Configuration form will be:
Page 30
Programming to use the Optional RJ-11 Cable
If the program is being built for a kV RSX that uses a communications cable with the RJ-11
(telephone jack) rather than the DB-9 (9 pin) connector, change the RSX Init setup string in the
Modem Configuration form as follows:
